I find the GorillaPod to be only adequate as a regular free-standing tripod. They work great if you use it as intended and wrap the legs around a fence post or tree branch, but as a stand alone tripod I have rarely been able to get it to comfortably support my 5DMII with a 24-70mm 2.8 lens.
I have the SLR-Focus model.
